Johnson Controls P499RCP-105 Pressure Transducer

The Johnson Controls P499RCP-105 is a high-performance electronic pressure transducer engineered specifically for the rigors of commercial refrigeration and HVAC applications. Built with a single-piece machined 17-4PH stainless steel pressure port, this unit eliminates internal O-rings and weld joints, providing a leak-proof seal that stands up to heavy pressure pulsations and vibration. It features a 0 to 500 psi range and a precise 0.5 to 4.5 VDC ratiometric output signal, making it a reliable choice for monitoring discharge pressure or condenser fan speed controls. The 1/4" SAE 45-degree flare internal thread includes a built-in Schrader valve depressor for streamlined direct-mount installation. With its 3-pin Packard electrical connection and environmentally protected electronics, the P499RCP-105 maintains a 1% total error band accuracy even in environments prone to high humidity, icing, and wide ambient temperature swings.

• Corrosion Resistance: 17-4PH stainless steel construction is compatible with ammonia, CO2, glycol, and most non-corrosive refrigerants.
• Durable Infrastructure: The all-metal, single-piece port design prevents refrigerant loss caused by seal failures or mechanical shock.
• High Precision: Delivers repeatable 1% accuracy across a broad compensated temperature range (-4 to 185?F).
• Ease of Installation: Slender body allows for use with deep-socket wrenches in tight mechanical spaces.
• Hazardous Location Rated: UL recognized for use in Class I, Division 2 hazardous environments.

What controllers are compatible with the 0.5 to 4.5 VDC output?
This ratiometric signal is typically used with specialized HVACR controllers that provide a 5VDC regulated supply, such as the System 450 or certain condenser fan speed controls.

Does this transducer require a separate wire harness?
Yes, the P499RCP-105 utilizes a standard 3-pin Packard connector; a compatible wire harness is required if you are not replacing an existing unit with a functioning plug.

Can I use this on the high side of an R-410A system?
With a 500 psi range, this transducer is suitable for many high-side applications, but always verify your peak system pressures do not exceed the 5x burst pressure rating for safety.
